REGISTER HOOD.

M invention relates to heating and ventilating apparatus and moreparticularly to a hood or cow for wall registers, by which outgoing orincoming air currents may be controlled and directed.

The invention contemplates a shelf-like hood or cowl, engage-able withthe upper end of the vertically disposed wall register in such relationas to overhang the register grid or grille to distribute and diffuse currents of warm or cold air emitted from such register, and particularlyto protect the wall area above such register from lodg ment of dirt,dust and grime. As is generally recognized, dust particles are carriedupward by the hot air currents, from a wall register of a heatingsystem, and not infrequently such hot air heating systems disperse moreor less smoke in the room. This smoke and dust particles find lodgementupon the wall. area above the register, presenting an un sightly andnnpleasing appearance. Moreover, the hot air through such register risestoward the ceiling. close to the wall of the room and is not ordinarilydiffused and distributed. It sets up air currents and eddies, passingdirectly from the register toward the ceiling of the room without areasonable amount of circulation and hence without giving off the heatunits.

The object of the present invention is to afford a simple, economical.but eflicient hood or cowl, easily applicable to ordinary wall registerswhich will tend to distribute and diiluse the air current from suchregis ters, and induce a wide circulation through the room, and avoidthe carrying upward of dust dirt and grime, to find lodgen'lent upon thewall immediately above the register.

A further object of the invention is to provide such a hood or cowlwhich will 3e capable of being knocked down or collapsed Serial No.533,204.

viously not necessarily the only form of embodiment of the invention,Fig. 1 is a perspective view of a wall register, to which the hood orcowl forming the subject matter hereof has been applied. Fig. 2 is aperspective view of the hood or cowl removed from the register andviewed from the rear.

Fig. 3 is a transverse sectional view of the assembled hood or cowlapplied to a register.

Like parts are indicated by similar characters of reference throughoutthe several views.

In the accompanying drawing, 1 indicates the wall register of ordinaryform, which as usually constructed comprises a grid or grille,surrounded by a border or frame 2, which normally bears against the wallsurface.

In the particular embodiment of the in vention illustrated in thedrawing, there are employed two oppositely disposed spaced heads or ends33, ofsubstantially triangular or bracketlike form. These heads or ends3 may be stamped from sheet metal or may be cast or formed from othersuitable material as is desired. These heads may be ornamented by anysuitable style of borders and panels, formed by embossing, indenting,marking, etching or otherwise as may be most convenient and suitable.The brackets or heads 3 are formed with marginal inwardly projectingflanges 4, along their upper edges. lnterposed between the heads 3 andoverhung by such marginal flanges l is a roof sheet 5, preferably thoughnot necessarily of sheet metal. This sheet 5 is inturned or rolled uponitself along its forward margin to form an integral tube or hollow roll6. The roof sheet extends thence downwardly and rearwardly following theoutline of the bracket or head 3, being deflected downwardly upon ashort radius as it approaches the plane of the wall. At a pointsubstantially on a level with the top edge or margin of the register 1,the roof sheet is flanged outwardly at 7, and thence downwardly at 8to-form an offset or rabbet for engagement over the top edge of theregister 1. The heads 3 and intermediate roof sheet 5 are held inassembled relation by tie rods 9 and 10. The tie rod 9 at the forwardangle of the bracket extends within the tubular marginal roll 6 of theroof sheet, and projects through the heads 3 at its opposite ends,

where it carries clamp nuts 11. The second tie rod 10 extends beneaththe roof sheet 5 and connects the brackets or heads 3 at approxi matelytheir upper rear angle. By means of these tie rods, the parts are firmlyand securely held in assembled relation to form a rigid hood structure,having the free downwardly extending blade or tongue 8 at its rear. BySlightly loosening the register 1 from the supporting wall, this bladeor tongue 8 forming the downwardly extended portion of the roof sheet 5,may be projected behind the border or frame of the register, as shownparticularly in Fig. 3, while the brackets or heads 3 bear against thefront face of the border or frame of the register adjacent to the endsthereof. The offset or shoulder 7 forms a seat which rests upon the topedge of the register frame, and upon which the brackets or headsfulcrum.

The bracket and roof sheet may be formed of any suitable convenient orpleasing contour. In the present instance, the roof sheet is ofsubstantially ogee shape, which for ordinary use will be found quitesuitable. The length of the hood or cowl agrees substantially with thatof the register, whereby the brackets or heads 3 may rest eitherdirectly upon the face of the register frame or border 2 approximatelyat the margins thereof, or upon the adjacent wall surface in closeproximity to the edge of the register frame. The brackets and roof sheetmay be of any extent whereby the hood may extend to a greater or lessdistance outwardly from the wall above the level of the register. Bydisengaging the clamp nuts from the tie rods 9 and 10 the structure maybe separated into component parts, permitting them to be arranged incompact form for convenient shipment or storage.

From the above description it will be apparent that there is thusprovided a device of the character described possessing the particularfeatures of advantage before enumerated as desirable, but whichobviously is susceptible of modification in its form, proportions,detail construction and arrangement of parts without departing from theprinciple involved or sacrificing any of the advantages.

lVhile in order to comply with the statute the invention has beendescribed in language more or less specific as to structu al features itis to be understood that the invention is not limited to the specificdetails shown, but that the means and construction herein disclosedcomprises the preferred form of several modes of putting the inventioninto effect and the invention is therefore claimed in any of its formsor modifications within the legitimate and valid scope of the appendedclaims.

Having thus described my invention, I claim:

1. A hood for wall registers comprising a shelf like deflector ofsubstantially ogee form, detachably engageable with the top edge of theregister plate and extending outwardly and upwardly therefrom and endbrackets detachably engaged with said defiector and bearing against theforward face of the register plate.

2. A hood for wall registers, comprising a deflector plate ofsubstantially ogee form terminating above the level of the upper edge ofthe register, the rear edge of which is offset and projected thencedownwardly from said offset to form a dependent marginal flangeeugageable behind. the upper part of a wall register upon the top edgeof which the offset formed in said plate is seated and terminal bracesfor said deflector plate resting against the face of the register.

3. A hood for wall registers comprising end brackets, an intermediatedeflector plate, a tie rod connecting the end brackets, the forward edgeof the deflector plate being bent upon itself to enclose the tie rod,and means independent of said end brackets for detachably engaging thehood with a well register, in overhanging relation.

4. A hood for wall registers comprising a pair of spaced bracket likeends, bearing upon the face of the register near the top thereof, and anintermediate deflector sheet detachably carried by the bracket likeends, the rear margin of which is adapted to rest upon the top edge ofthe register and project thence behind the register to support thestructure in overhanging relation.

5. A hood for wall registers or the like comprising a shelf likedeflector of substantially ogee form, and end walls connected thereto,the structure being engageable with the top margin of a wall registerwith the deflector plate extending outwardly and upwardly therefrom, therear margin of the deflector plate and the end walls being spaced apartto enable the structure to straddle the margin of the register with themargin of the deflector plate engaging the rear face and the end wallsengaging the front face of the register plate.

6. A hood for wall registers, comprising a shelf like deflectorextending outwardly and upwardly from the top edge of a wall register ininclined relation to the plane of the register, and substantiallytriangular end bracket-s, one side of each of such triangular bracketsbeing alined with the register, said end brackets being engaged with theshelf like deflector, the rear margin of the deflector and said endbrackets engaging to the rear and in front of the wall registerrespectively in straddle relation with the top margin thereof.

In testimony whereof, l have hereunto set my hand this 13th day ofJanuary A. D. 1922.
